WASHING- MACHINE.

SPECIFICATION forming' part of Letters Patent No. 755,742, dated March29, 1904:.A

Application filed May 2B, 1903.

To a/ZZ whom it may concern:

Be it known that I, HENRY EMIL OARsTENs, a citizen of the United States,residing at Davenport, in the county of Scott and State of Iowa, haveinvented new vand useful Improvements in Vashing-Machines, of which thefollowing is a speciication.

This invention relates to improvements in washing-machines, and hasparticular reference to that class in which a rocking or swinging bodyand agitator are employed.

The object of the invention is to provide a washing-machine which willbe simple in construction durable in use, and eiiicient in its operationand wherein the clothes are thoroughly and rapidly cleansed with theleast possible amount of agitation, to the end that tearing or otherinjury to the fabrics is obviated and exertion on the part of theoperator reduced.

Heretofore in washing-machines of this type the agitator for the clotheshas been mounted so as to swing in a direction opposite to that of thebody, thereby causing the same to act as a rubber and to force theclothes in a direction contrary to the movement imparted thereto by therocking of the body. This action results in an unnecessary amount ofagitation and injury to the clothes and requires considerable effort tooperate the machine; but the present invention is designed to preventthese difficulties by providing means for swinging the agitator in thesame direction with the body containing the clothes and accelerating themovement of the former, whereby the clothes will be carried and held bythe agitator at each oscillation of the body and will act as a sievethrough which the water will percolate to thoroughly clean the same,while at the same time permitting the 4clothes to gradually fall to thebottom 0f the Serial No. 158,814. (No model.)

`\washingmachine constructed in accordance with my invention. Fig. 2 isa central vertical longitudinal section showing in dotted` lines theposition of the parts when the body v isswung in one direction. Fig. `3is a perspective view of the agitator and its hangers removed from themachine. Fig. 4 is a fragmental view in vertical transverse section onthe line of Fig. 1, showing thev relative `arrangement of one of thetrunnions with the parts of the machine.

In the drawings similar reference-notations indicate the same partsappearing inthe several illustrations, and reference being made to thedrawings, 1 designates a frame of such shape asmay be fixed upon to meetthe purposes of its use. This frame comprises two pairs of legs 2 3,which are braced around the lower ends thereof by suitable stays 4, andon the upper end of each pair of legs is mounted asocketed casing or cap5, having a transverse aperture to receive the trunnion 6, which islocked therein by means of a set-screw 7. Each of the trunnions 6 isformed at its inner end with a right-angular extension 8, from the endof 'which projects a lug or pin 9,' arranged in the plane above theportion 6, thus forming a crank-shaped member, the function for whichwill hereinafter be pointed out.

The body 10 of the machine consists of a semicylindrical receptaclehaving the usual corrugated metal lining 11 and provided on its top witha hinged cover 12. The body is further provided.with a pair ofoutwardlyextended arms 13, which are connected at their outer endswithva handle-bar 14, and at its opposite end there is formed a cleat15, adapted to receive a wringer, which is not shown in the drawings.From this cleat 15 extends a downwardly-inclined drain-board 16 forconducting the water into the machine when the clothes are being wrung.The body 10 is mounted for oscillation between the legs 2 and 3 of theframe, being journaled on the trunnions 6.

On the inner side of the cover 12 are twoV pairs of ears 17, betweenwhich are pivoted the depending hangers 18 of the agitator. Thesehangers are bifurcated at their lower ends, as at 19, .in whichbifurcation the lugs IOO 9 of the trunnions engage and slide when thebody is rocked on its journal. To provide for conveniently engaging thelugs 19 in the bifurcations of the hangers, the latter are provided attheir lower ends with beveled or rounded corners 20. The hangers areconnected near their lower ends by a block or cross-head 21, in which ismounted the depending stem 22 of the agitator 23. This agitator isloosely mounted on the stem 22 to per-` mit it to slide verticall Y orrotate to accommodate the amount of c othes in the washingmachine, andfrom its bottom project the usual pins 24, which engage the clothes tohold them elevated at the endof each oscillation of the body.

From the description thus far given it will be perceived that theagitator is carried by the body and that it is permitted to swingindependently of the same by means of its pivotal connection with thecover of the body; but its movements are controlled by the movements ofthe body, and those movements are alwaysin the same direction with thebody.

As stated in the preliminary portion of the specification, the motion ofthe agitator is accelerated with relation to the motion of the body, andthis is accomplished by the fulcrum for the agitator (Which comprisesthe lug 9 in the bifurcations 19) being in a plane above the fulcrum ofthe body, whereby when the body is rocked on its journal 6 the hangers18are carried with it and the latter slides on the lug 9, causing theagitator to be moved faster up toward the top of the body.

Secured' at one end to one of the braces 4 is a coil-spring 25, which isengaged at its other end with the body 10 and which acts to assist thereturning motion from the end of each oscillation and always causes thebody to assume its normal position when left at rest'.V

To one of the legs 2 is secured a hook 26, adapted to engage an eye 27on the side of the body when the machine is at rest and water or clothesare being introduced or removed therefrom.

The operation may be briefly stated as follows: It being premised thatthe required amount of clothes to be washed is contained in the body andwater has been introduced, the operator rocks the body on its journal 6.Referring to Fig. 2 of the drawings, the parts are shown in dotted linesin the positions they occupy when the b'ody has been rocked in thedirection of the arrow, and upon this movement the clothes, which arenormally at the bottom of the body, are engaged by the pins 24 of theagitator and carried upwardly therewith, while the water will percolatethrough the clothes and fall to the opposite end of the body. Theagitator being revoluble and slidable on the stem 22 will permit theclothes to gradually fall to the bottom of the body, so that upon thenext oscillation of the latter the clothes will be again engaged by thepins tion.

and carried to the opposite end of the body, while the water willagainpercolate therethrough, this operation being repeated until the clothesare thoroughly cleansed.. The accelerated movement of the agitator tendsto push the clothes up against the top of the body and in a measurecompressing them to rinse the water therefrom, and this continuousrinsing action hastens the washing opera- It may be further explainedthat the accelerated4 movement of the agitator is due to the fact thatthe fulcrum-lug 9 constantly changes its position in the bifurcationduring the movement of the body, such change emanating from the slidingconnection between the lug and the hangers, which increases thevdistance between the pivotal connection of the hangers with the coverand the lug, which is stationary. Y

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-
